Dr. Mushlin is a research staff member in the Functional Genomics and Systems Biology group of the Computational Biology Center. He received a Ph.D. degree in chemical physics from Brandeis University in 1979, and joined IBM in 1982. Dr. Mushlin's long and diverse career at IBM includes developing an experimental MRI system, managing a software development group, deploying a World's Fair kiosk system, designing clinical information system applications, and most recently, developing tools and methods for clinical genomic data analysis.

Aaron Kershenbaum  IBM Thomas J. Watson Research Center, P.O. Box 218, Yorktown Heights, New York 10598 (aaronkus.ibm.com). Dr. Kershenbaum is a research staff member in the Systems department at the Thomas J. Watson Research Center. He received B.S.E.E and M.S.E.E. degrees simultaneously in 1970 from the Polytechnic Institute of Brooklyn and a Ph.D.E.E. degree in 1976 from Polytechnic University. He joined Network Analysis Corporation in 1969, where he helped design some of the earliest computer networks, including the ARPANET and NASDAQ. In 1978, he joined the faculty at Polytechnic University, where he helped develop a curriculum in computer communications and served as Director of the Network Design Laboratory. He joined IBM in 1990, where he has done research in applying network theory to problems in communications network design and analysis, computational biology, computational linguistics, and interactions among concepts in ontologies. He received an IBM Outstanding Innovation Award for his work in computer network design. Dr. Kershenbaum is a member of the ACM and a Fellow of the IEEE.

Stephen T. Gallagher  University of Pennsylvania, Blockley Hall, 423 Guardian Drive, Philadelphia, Pennsylvania 19104 (sgallaghcceb.med.upenn.edu). Mr. Gallagher is a Programmer Analyst in the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania School of Medicine. His work in LIMS development and genetics databases supports the Laboratory for Molecular Epidemiology. His primary research interests lie in efficient data management of large-scale study data and novel methods of pattern detection.

Timothy R. Rebbeck, Ph.D.  University of Pennsylvania, 904 Blockley Hall, 423 Guardian Drive, Philadelphia, Pennsylvania 19104 (trebbeckcceb.med.upenn.edu). Dr. Rebbeck is Professor of Epidemiology, co-leader of the Abramson Cancer Center's Cancer Epidemiology and Risk Reduction program, Director of the Center for Genetics and Complex Traits, Director of the Center for Population Health and Health Disparities, and Director of the Laboratory for Molecular Epidemiology at the University of Pennsylvania School of Medicine. Dr. Rebbeck's research focuses on the genetic and molecular epidemiology of cancer. He has directed several molecular epidemiologic studies whose goals were to identify and characterize genes that are candidates for involvement in cancer etiology, and to describe the relationship of allelic variation of these genes with biochemical or physiological traits, cancer occurrences, and cancer outcomes.
